* docs(#1610): ADR for the workflow/agent size-budget ratchet
Gives the already-shipped size-governance decision (epic #1074; PRs #1089/#1096/#1097) its first ADR: per-file LF-normalized byte baseline (anti-creep across every workflow/agent .md) + loose tier hard caps (XL/LARGE/DEFAULT), measured in bytes not lines, with an explicit do-not-game-the-proxy clause (lazy extraction only). Distinct from the install-time skill-surface budget of ADR-0010/0011.
Verified against tests/{workflow,agent}-size-budget.test.cjs + scripts/workflow-size.cjs: cap constants XL_CAP=98304/LARGE_CAP=61440/DEFAULT_CAP=40960/NEW_FILE_CAP=32768, and the largest XL orchestrator is plan-phase.md (~93,973B) ahead of execute-phase.md (~93,426B) — corrected from the draft.
Closes#1610.
* docs(#1610): de-rot tier-cap byte figures — cite baseline JSON not a drifting snapshot
